Mozilla Suggests Privacy-Protecting Approach for Personalizing Online Content

Mozilla is floating a new idea that would let browsers personalize Web content without needing to access a user’s entire browsing history as is the case now. If adopted, this interface would give users control over information their browser shares with websites and eliminate tracking systems used by advertisers that typically access a user’s entire browsing history. Such information is typically used to deliver content, such as advertisements, to a user based on sites or information previously viewed. The history can also be accessed without the user’s consent, which is a problem for privacy. The Mozilla Labs Prospector research team developed its new approach by conducting opt-in experiments with volunteer users. Mozilla’s new Firefox browser design would use artificial intelligence to learn a user’s interests over time and make relevant content available. (SlashDot)(Engadget)(CNET)(Mozilla)

Researchers Design Secure Browser

University of California, San Diego, computer scientists have developed a secure browser design that uses a new security verification approach. Typically, browser security is based on a model or abstraction and not the actual browser. Hackers can exploit the gap or difference between how the browser functions in the abstraction and actual browser. The researchers’ formal shim verification technique corrects this by formally proving that the browser implementation itself is correct by using a proof assistant to determine if the code meets the specifications. The researchers tested their approach on a browser they created called Quark. Verification is typically time-consuming and requires a great deal of code; however, formal shim verification creates a small browser kernel. It is only this part of the code in their browser – the portion most vulnerable to attack -- that is verified. The researchers presented their work at the 21st Usenix Security Symposium.
